办美国签证需要中英版的在职证明，麻烦帮忙看下以下两段翻译哪个比较好。
此次旅游的所有费用包括：机票费，住宿费和医疗保险等均由她本人承担。我们保证她在国外旅游期间将会遵守当地的法律法规。我们也保证她将会按时回国并继续在我公司工作。特此证明！
She will be responsible to settle all the travel expenses including airfare, accommodation and health insurance. We can assure that she will comply with local laws during her visit in America. We can assure that she will return to China on schedule and we will keep her position during her visit to America as well.

All the travelling expenses, including air tickets, transportation, accommodation and health insurance, will be covered by herself.
We hereby guarantee that she will abide by all the laws and regulations during his staying abroad. We also guarantee that she will be back to China on schedule and will continue to work for our company.
还有这段应该怎么翻好“她将于2015年06月03日到2015年06月18日赴美国旅游。”
